Fuel Pump Controller (FPC) Diagnostic Jumper

More uses than a 10MM socket! Keep this jumper tucked away in your glove box in case of an emergency. Diagnosis Tool Typically, when a fuel pump controller fails, it works intermittently and eventually stops working altogether. If you aren't sure where the fuel problem lies, don't buy a new fuel pump or controller just yet. Instead, eliminate the fuel pump controller as a variable by installing the iWire FPC jumper in its place. If the fuel pump works correctly with the jumper in place of the FPC, then it's time to replace the FPC. Are you looking at trying to diagnose your FPC or P0230 code? Start by clicking here. Empty Your Fuel Tank Plug the jumper in, turn the key to the on position, disconnect the fuel feed line, and drain the fuel into your bucket of choice to save for another adventure.  Great for tuners and shops looking to quickly swap between different fuel types (91 to E85) on the dyno. If you have a car in long-term storage, easily drain or replace the fuel in the tank so that when it is ready to drive again, it fires right up.  Roadside Rescue The OEM fuel pump controller (FPC) can even fail with our hardwire kit from time to time. Just plug this little adapter in, get yourself off the side of the road, and home for a fix. It even comes with a handy dandy carabiner!
